1.3 Specifications
1.3.1
Dosimeter carries out continuous measurement of the DER, DE and DE accumulation time in all
operation modes except for the computer communication mode.
1.3.2
Operating mode:
-
DER measur
ement;
- DE measurement;
- settings;
- current time indication;
- battery status indication;
- DER measurement start;
- communication with computer.

1.3.8
Dosimeter allows setting two DER alarm threshold levels and two DE alarm threshold levels. Dosimeter
continuously controls the threshold levels and alerts the user with sound, light (red colour) and vibration
alarms when the threshold level is exceeded. Flash signal for the fist DER threshold and fast flash - for the
second DER threshold exceeding.
DER thresholds setting range: 0.01 µSv/h to 10.0 Sv/h
DE thresholds setting range: 1.0 µSv to 20.0 Sv
Threshold setting resolution − low order digit.
1.3.9
Photon radiation energy range
0.02 to 10.0 MeV
Energy response relative to 0.662 MeV (
137
Cs) in the
DER and DE measurement mode, no more than
-
60 % from 20
to 33 keV;
- 40 % from 33 to 48 keV;
 30 % from 48 keV to 3 MeV;
 50 % from 3 to 10 MeV.
1.3.10 Anisotropy of the dosimeter


for each energy does not exceed the values shown in Table 1.2 when
dosimeter is irradiated in the horizontal plane at indicated angles relative to the initial direction, and does not
exceed the values shown in Table 1.3 when the dosimeter is irradiated in the vertical plane at indicated angles
relative the initial direction.
